Multiple-use transport unit for sheet-material rolls and the like

ABSTRACT

The invention relates to a modular-construction storage and transporting unit ( 1 ) for a roll ( 2 ) made of a material web, in particular a sheet-material strip, which is wound up on a winding core. The storage and transporting unit ( 1 ) comprises a support in which fork tines of an industrial truck can engage. The storage and transporting unit also comprises at least two supporting walls ( 3 ), which are arranged opposite one another in the roll-transporting position and each have at least one plug-in opening ( 4 ) for accommodating one end of the winding core, and/or allow a retaining sleeve ( 6 ) to engage through them, in which case the roll is accommodated axially between the supporting walls ( 3 ). The support here is formed from at least two supporting runners ( 7   a ), wherein, in the roll-transporting position, the supporting runners ( 7   a ) are arranged at a distance apart from one another, and preferably parallel to one another, and the supporting walls ( 3 ) are arranged, and retained, on these supporting runners.

The invention relates to a storage and transport unit for foil rolls and the like according to the preamble of patent claim 1.

In order to transport plastic foil and other material webs from the manufacturer to the user or processor, continuously produced foil webs are wound onto rolls at the manufacturer, mostly paper rolls, so-called winding cores, into a coil. Depending on the width of the foil web, such coils have different axial lengths, wherein axial lengths of 1700 mm are quite possible. Depending on the width of the foil web, the winding length, plastic material and material thickness, such coils can have a mass of up to 600 kg and above.

In order to transport such coils safely and without damages from the manufacturer to the user, therefore, suitable transportation packaging is required, which shall prevent a tilting or roll off of the coil, depending on the transport position or transport orientation of the coil. For this purpose, transport units with wooden pallets are known wherein upward oriented plywood sheets are mounted at a distance from one another at the narrow sides or long sides of said wooden pallets, which serve as support walls for the coils. Said plywood sheets, which are substantially configured square, typically comprise a circular opening or insertion opening. Between said two square plywood sheets, the coil is subsequently disposed in axial direction, so that the ends of its roll type winding core match the openings in the plywood sheets, and are held by retaining sleeves for the rolls, which are run through the openings of the plywood plates from the outside. The coil is thus secured by the plywood sheets at its two axial ends in axial direction, and secured in radial direction by the sleeves, engaging its winding core. By placing the respective plywood sheets on top of one another, transport units with several coils disposed on top of one another can be configured.

In order to mount the plywood sheets to the wooden pallets, preferably steel U-profiles are being used, which are fixated to the wood pallets with their bases nailed down or screwed down, wherein their arms are oriented upward with reference to the pallet loading surface, so that the respective sheet metal plate can be inserted between said arms and secured by nails, bolts or similar. For securing several plywood plates next to one another or above one another, double-U-profiles can be used in a similar manner. Quite frequently, such a packaging for coils is eventually enclosed with a shrink foil or with straps, in order to further increase the stability of the transport unit.

A substantial disadvantage of said transport units is that the various single elements of the transport unit, these are the pallets, the plywood sheets, the insertion sleeves, the U-profiles, the rolls (winding cores) and various small fastening means for assembly have to be disposed of at the user. The reason is among others that the wood components of the packaging are mostly not configured for multiple-use. For the manufacturer of the foil web, this means a tremendous logistical effort, in order to continuously provide the single components for producing the transport units or packaging units, which also comes at a high cost. On the other hand, such throw-away solutions are non-satisfactory from an environmental point of view.

Furthermore, there is the problem that the packaging components formed from wood, in particular the plywood sheets, can absorb moisture, and thereby then lose their strength. Therefore, said transport units mostly cannot be stored over a longer period of time. This basic problem also occurs when the transport units are exposed to rain, e.g. on an uncovered truck bed.

It is the object of the invention to provide a storage and transport unit for wound-up plastic foil webs (coils) and similar with simple and robust construction, which provides a simple assembly of the transport unit, and a safe reception of the coil, while reusing the unit several times. Simultaneously, a space saving return of the transport unit shall be facilitated.

The object is accomplished by a storage and transport unit according to the features of patent claim 1. Advantageous embodiments are objects of the dependent claims.

It is provided according to the invention to provide a storage and transport unit, which is substantially configured, so that its modules can be combined among one another, depending on the respective storage or transportation requirement. Simultaneously, the modules, however, are adjusted to one another and configured, so that a space saving retrieval transport of the modules is possible. Through the design configuration of the modules forming the storage and transport unit, thus a space saving retrieval and the reuse of said components is facilitated, so that said modules can be used for a long time for forming respective transport units.

The components of the storage and transport unit are advantageously made of plastic, in particular, however, from recycled plastic. This takes environmental considerations into account. By forming the components, and thus also, the storage and transport unit assembled thereof from plastic, a resistance against moisture, in particular rainwater, is advantageously provided.

Through the subsequently described measures, the support walls and also the support skids are configured very stable, and simultaneously weight saving. In particular, the latter also takes the idea of retrieval into account.

Through the stable configuration of the support skids and of the support walls as hollow components with a closed surface, which is advantageous for cleaning purposes, or as components flat closed surfaces at the visible side with ribs or support bars disposed on the back wall, and a simpler support assembly and mounting technology of the components forming the storage and transport unit, the best stability is provided for the coils to be transported, which improves safety, in particular, when loading such storage and transport units. This is important, in particular, due to the sometimes high masses of such coils of up to 600 kg and more.

According to the invention, the support walls are held by a form locked engagement of engagement members into a corresponding recess in the support skids or vice versa, and additionally they are mounted with plural mounting mechanisms (e.g. clamping elements), whereby compared to current solutions, a very stable configuration for the coil receiver is provided.

Simultaneously, the distance of the support walls, offset parallel from one another, can be adjusted, so that the coil (or the coils, if several coils are to be received in a storage and transport unit) can be exactly inserted according to the length of its winding core or even with a slight oversize, whereby overall an additional stabilization of the storage and transport unit is provided, so that the overall configuration of such a storage and transport unit has a stability, which has not been reached in the state of the art so far.

Additional advantages can be derived from the embodiments described in the figures. It is shown in:

FIG. 6 the actual configuration of a mounting mechanism for the support walls on the support skids.

FIG. 1 a shows a storage and transport unit, designated 1 for a wound-up foil web (coil) 2. The coil 2 is held in axial longitudinal extension between two lateral components and two support walls 3, so that the longitudinal axis of the coil substantially corresponds to an orthogonal of the main plane of extension of the support wall 3. The main surface of the support walls 3 is substantially configured square, but can also be configured rectangular.

A support wall 3 comprises a thickness which is small compared to the lateral dimensions of the main surface. Preferably, a lateral length corresponds to an integer multiple of the thickness. The support wall 3 comprises plural pass-through openings or insertion openings 4, which extend from the forward main plane, substantially perpendicular through the support component 3, and which are circular, wherein an insertion opening 4 a is disposed in the center of gravity of the main surface, so that the axis of said central pass-through opening 4 a substantially extends through the intersection of the diagonals of the main surface. The support wall 3 is provided with recesses or indentations 5 at least at one lateral surface or rim surface, whose function is described in more detail infra. Said indentations or recesses can be configured so they pass through or with interruptions.

A centering or mounting sleeve 6 at each respective axial end of the coil 2 holds said coil in its position. For this purpose the mounting sleeve 6 is inserted or turned in or similar from the easily accessible main side (front side) of the support wall 3 through an insertion opening 4 or 4 a (as illustrated in FIG. 1 a by the central pass-through opening 4 a) and reaches into the interior of the winding core, which is not shown, onto which the foil web is wound, so that it is fixated in axial direction and also in radial direction with a larger or smaller clearance. The centering or mounting sleeve 6 can be provided at one end with an axially outward protruding flange, which forms a stop upon insertion, and thus avoids a slippage through the pass-through opening 4 or 4 a.

The support walls or holder components 3 are disposed on two skid type base components, so-called support skids 7, wherein the lateral components 3 span the support skids disposed parallel relative to one another in the assembly according to FIG. 1 a. According to the illustration, the support walls 3 are disposed at the ends of the support skids 7. The distance of the two support walls 3 on the skid type foot components 7, however, can be variably adjusted to the length of the respective winding core of the coil. The support or mounting mechanism, in particular the mounting mechanisms 15 illustrated in the figures, between the support walls or the support components 3 and the support skids, will be described in more detail infra.

The support skids 7 comprise an axial longitudinal extension, which substantially corresponds to a multiple of the width or of the height of their cross section. Preferably, the length corresponds to an integer multiple of a side length of the support walls 3. Similar to the support walls 3, also the skid shaped bottom components 7 comprise at least one recess or indentation 8 on their upper side. Furthermore, the support skids 7 can be provided with recesses 9, which facilitate the engagement of a lifting tool (e.g. the forks of a forklift). For reasons of stability, said recesses 9 are preferably completely enclosed, this means surrounded by material towards all lateral side surfaces, so that there still is a bar of material above and below the recesses 9.

When preparing the transport unit according to FIG. 1 a, the substantial advantage relative to the state of the art is accomplished, since the distance of the two support walls 3 can be adjusted without any problem to the axial length of the roll, this means of the winding core, on which the foil web is wound up. The illustration of FIG. 1 a, in which the two support walls 3 are respectively disposed at the ends of the support skids 7, is thus only a special case. In case of shorter rolls, it is possible, in order to avoid too large an overhang, to provide the support skids 7 in an alternative shorter length, like e.g. the support skids 7 a according to FIG. 1 b. Said shorter support skids 7 a as well as longer support skids, which are not shown, are thus always components of a modular assembly of said transport unit. In any case, the length of one support skid 7 or 7 a advantageously corresponds to an integer multiple of a lateral length of a support wall 3.

FIG. 1 shows a transport unit 1 which is substantially already known from FIG. 1 a. Different from the transport unit of FIG. 1 a, said transport unit, however, comprises two foil coils 2, which are disposed on top of one another and which comprise an identical axial alignment. For this purpose, the support walls 3 are disposed at each axial end of the coils 2, so the support walls stand on top of one another, so that their rim surfaces, facing each other, substantially overlap completely.

The advantage of said configuration of a transport unit for foil rolls and similar is that an optimum utilization of an available transport volume, e.g. in a freight container or on a truck bed, can be accomplished. In the transport units according to the state of the art, such an arrangement of coils on top of one another is mostly problematic, since the plywood side pieces held by a double U-profile only have a small contact surface (force transfer surface), with respect to one another, which makes the overall assembly shaky and prone to collapsing, so that a transport unit thus prepared generally has to be stabilized by an additional shrink foil or by a tightening strap.

FIG. 1 d shows two storage and transport units according to FIG. 1 a, which are combined into a common storage and transport unit, so that the two coils 2 are disposed more or less lying next to one another having the same axial orientation. In the center, a support skid 7 b is provided, which is provided respectively wider, and which advantageously comprises also two recesses 9 at its upper side. By preparing a storage and transport unit in this manner, the loading effort can e.g. be substantially reduced.

FIG. 2 a shows the elements already known from FIGS. 1 a-1 d in an alternative arrangement, which is preferably suitable for transporting coils with smaller diameter. The support walls 3 a, which are used here, are also configured with a square perimeter, however, with shorter side lengths than the plate shaped holder components 3 according to the FIGS. 1 a-1 d. The support walls 3 a are disposed according to the illustration in FIG. 2 a in longitudinal direction (this means with the same alignment as the support skids 7 or 7 a) and standing on the support skids 7 a, which are shown in short configuration here only for exemplary purposes, so that the received or retained coils extend axially transversal to the two parallel support skids 7 a and are disposed lying next to one another. It is certainly also possible according to the overall module idea to provide a larger side piece 3 according to the FIGS. 1 a-1 d in the same manner on the support skids 7 or 7 a.

FIG. 2 b shows an improvement of the configuration of the storage and transport unit according to FIG. 2 a configured, so that two additional coils are placed quasi in a certain type of second level on the coils, which are the lower ones then, wherein the longitudinal axes of all coils substantially comprise the same orientation and are aligned in parallel in all three dimensions. It is certainly also possible to only dispose one coil in the upper level, e.g. in the center relative to the two lower coils. By the same token, it is also possible to additionally dispose a third level of additional coils by disposing and mounting additional support walls, which can furthermore also comprise other square or rectangular lateral dimensions according to the modular concept.

FIG. 3 shows an additional storage and transport unit using the components or modules described supra. As it is evident from FIG. 3, a plurality of coils 2 a is received lying flat in the storage or transport unit, so that the longitudinal axes of the winding cores substantially extend vertically. Such an assembly is suitable in particular for coils, whose width with respect to the wound-up material or foil web is less than the diameter of the coil itself, or put differently, whose diameter is larger than their longitudinal extension. Depending on the diameter of the coil or depending on the width of the wound-up material web, the coils can be disposed quasi standing next to one another, behind one another, and/or on top of one another. According to FIG. 3, a total of 56 coils are combined in a 4×2 arrangement with seven layers or levels each in the storage or transport unit. For this purpose, the support walls 3 or 3 a described supra are disposed lying flat and fixated on two parallel offset support skids, bridging them. According to the illustration, exactly two side pieces 3 a are used lying next to one another. Since the side pieces 3 a thus have to bear the entire weight of the short coils 2 a, they have to be designed according to this application. However, it is also possible as shown in FIG. 3 to dispose additional support skids 7 or 7 a below the flat lying support walls 3 or 3 a in order to support the load.

In this embodiment, the coils of the lowest layer reach with their downward facing winding core ends into the insertion openings 4 of the lateral components 3 or 3 a, which are disposed lying flat on the support skids 7 a. Thus, also adapters in the form of reduction or centering sleeves can be provided (not shown). In order to support and stabilize the entire storage or transport unit, support walls 3 or 3 a can also be placed on the coils 2 a of the uppermost layer or level. As illustrated, the two levels can be separated by intermediary layers made of wood and/or plastic, or other suitable materials, which can simultaneously also form a lower or upper termination for the support walls 3 or 3 a. The axial alignment of the coils 2 a, disposed in a vertical row on top of one another, can be performed by the intermediary layers, but also by connection adapters or by other suitable measures. After preparing such storage or transport unit, it is furthermore possible to apply tightening straps and/or a shrink foil eventually, in order to stabilize the entire assembly.

From the description of the previous embodiments, this means form the disposition and assembly embodiments for the components or modules, it is evident that also within a storage or transport unit, different disposition concepts can be combined with one another, so that it is entirely possible to combine longitudinally and transversally lying coils with standing coils in a storage or transport unit.

FIGS. 4 a-4 c show combination options for so-called storage and/or retrieval transport units of the particular modules described supra for the retrieval transport. The components of a storage or transport unit are configured so that they can be assembled or combined in an optimum manner for the retrieval transport, in order to utilize, on the one hand storage volume, and on the other hand, an available transport volume in an optimum manner. According to FIG. 4 a, plural support skids are combined and form a carrier with a quasi closed pallet loading surface. In an advantageous manner, thus support skids with equal length are combined. On the combined support skids, the support walls, which are combined in a pack now, can be disposed standing upright and they can also be mounted advantageously. In order to facilitate a uniform alignment of the support walls and also to avoid slippage during transport, the support walls comprise centering members or centering studs 10 at their front sides and they comprise complementary centering recesses 14 (re. FIG. 5) at their backsides. In the storage or retrieval assembly according to FIG. 4 a, the centering members of the front sides engage in a form locking manner with the respective centering recesses of the backsides of the respective adjacent support wall. In an advantageous manner, support walls of equal size are combined according to the illustration in FIG. 4 a. However, it is also conceivable to configure the pattern for the centering members or for the centering recesses, overall the same for all sizes of support walls. This has the advantage that also support walls of different sizes can be combined with one another in a pack.

According to the illustration in FIG. 4 a, it is advantageously provided that the support walls are disposed transversal to the longitudinal direction of the support skids. As it is also apparent from FIG. 4 a, additional support skids can be combined and can be arranged, so they form a type of upper termination on the support walls combined as a pack. It is also possible to dispose additional support skids below the support walls, which then form several levels. By the same token, it is possible to combine a retrieval transport unit, which is only comprised of support skids, preferably comprising the same length.

FIG. 4 b shows the assembly according to FIG. 4 a in an exploded view. As it is evident, the tunnel type cavities, which are formed by the insertion openings of the support walls combined in packs can be simultaneously used for the retrieval transport of the winding cores 13 and of the centering- and mounting sleeves 6, which are inserted into the tunnel shaped cavities, and which can be secured by inserting centering- and mounting sleeves 6 against sliding out or falling out. In an advantageous manner, the inserted winding cores stabilize the retrieval unit internally by at least preventing a slipping of the support walls relative to one another.

FIG. 4 c illustrates a retrieval unit, in which the support walls are disposed lying flat on the support skids, wherein in turn, the centering members of a support wall engage the centering recesses 14 of the backside of a support wall disposed above it, thus stabilizing the packet type stacked combination. As described above, winding cores can be inserted again into the respective tunnel shaped cavities, which are in turn formed by the insertion openings of the support walls.

FIGS. 4 a-4 c are only examples for the configuration of a retrieval unit. A retrieval unit can certainly also be combined in another manner, e.g. by combining the previously described embodiments. In order to stabilize a retrieval unit, it is furthermore possible to use additional tightening straps and/or a shrink foil or similar.

In FIG. 5, the actual configuration of a support wall is illustrated in an exemplary manner. In the left part of FIG. 5, the front side of a support wall 3 a is depicted. In the support wall 3 a, five insertion openings 4 are configured, wherein one insertion opening 4 a is centrally located. Furthermore, four centering members 10 are disposed on the front side, wherein said centering members are provided as protrusions. In the upper rim surface, an indentation in the form of a recess 5 is provided, wherein said recess is only configured as a pass-through in an exemplary manner. At the lower rim surface, this means at the rim surface opposite to the rim surface, comprising the recess or the recesses 5, two engagement members in the form of protruding lugs, in this case lugs or pins protruding downward, are provided.

In the right section of FIG. 5, the backside of the support wall 3 a of the left image side is illustrated. The disposition of support and carrier ribs is clearly visible, wherein said disposition is only shown in an exemplary manner. The four centering recesses 14 are also visible, into which the centering members of the front side of a support wall, which is adjacent in the stacked combination, interlock in order to align the particular support members in this stacked combination or in this packet type assembly, and in order to stabilize the overall assembly. Alternatively, a support wall can also be configured with a closed surface on the backside. The support walls are advantageously always integrally configured from plastic and they are produced in an injection molding process. The support walls are formed in particular from a recycled plastic or from scrap materials of the foil webs to be transported.

In the explosion drawing of FIG. 4 b, the engagement members 12 are visible, which engage the groove type depressions or recesses 8 on the upper side of the support skids in an interlocking manner in order to form a storage or transport unit or also a retrieval transport unit. The same applies for the support walls disposed on top of one another according to the illustrations in FIGS. 1 c and 2 b, wherein the engagement members engage the recesses 5 on the upper rim surfaces of the support walls disposed below. It can be provided in case of a flat lying arrangement of a support wall 3 or 3 a on the support skids that engagement members engage the recesses 8 of the support skids on the front sides of the support walls. These technical measures thus are used for supporting the support walls on the skids. The fixation is described subsequently.

An exemplary mounting mechanism for the support walls on the support skids is described in FIG. 6, which shall provide a sufficient stability to the storage and transport unit, which is assembled from the components and modules. The mounting mechanism is preferably provided as a clamping element 15. For this purpose, a clamping pinion is disposed flush on one side in a ball joint at the front side of the support skid 7 or 7 a. At the end of the clamping pinion 16, which is disposed opposite to the ball joint, a clamping latch 17 is mounted by a threaded connection, wherein the main axis of the clamping latch 17 extends perpendicular to the main axis of the clamping pinion 16. In order to mount a support wall to a support skid, the support wall is placed on the support skid, so that its downward protruding engagement members engage the upper side of the support skids in an interlocking manner (creation of a support combination). The clamping pinion 16, disposed flush in a recess of the support skid, is pivoted about the ball joint until the clamping pinion 16 together with the clamping latch 17 engages a correspondingly configured recess in the support wall. By rotating a clamping pinion 16, e.g. with an open-end wrench, the clamping latch 17 is pulled against a correspondingly configured support surface, which eventually leads to a clamping of the respective support wall on the support skid. Such clamping elements per se are known in the state of the art, however, from other areas of applications. Therefore, they need not be described in more detail.

Such a clamping element 15 can certainly also be disposed at other locations of the support skids or for example also in the support walls. Alternatively, it is possible to provide such clamping elements as loose components, which are then inserted at the respective connection locations into the recesses provided only when needed.

From the description of the embodiments given supra, the modular concept becomes evident in particular, which provides that the respective components can be provided in different dimensions, and can still be combined among one another for providing a storage or transport unit or a retrieval transport unit, this means they can be arranged and mounted relative to one another.
